[Fab] MoI 3d

Has anyone used Moment of Inspiration (http://moi3d.com/) to generate 3d
models for printing? I am trying it out now, they've got a Mac beta
version, and I'm liking it a lot. My main desire is the ability to do
complex curves, and for that, I have gotten better results from an hour
with MoI than from a day and a half with Blender. I'll bring my stl in
on Wednesday if I can, try to print it out!
